What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: To evaluate the impact of Nafamostat mesylate (NM) in improving survival outcomes among rats subjected to exertional heat stroke. Methods: This study involved a cohort of 45 specific pathogen-free (SPF) male Sprague Dawley (SD) rats. After successfully inducing exertional heat stroke, the rats were randomly divided into three groups: the Control group (Con, n = 15), the Exertional Heat Stroke group (EHS, n = 15), and the Nafamostat Mesylate group (NM, n = 15). A subset of ten rats from each group was selected for a 72-h survival analysis. Three hours following the successful establishment of the model, blood samples were collected under anesthesia for comprehensive analysis. This included routine hematological tests, coagulation assessments, and quantitative proteomics analysis, which were later validated using Parallel Reaction Monitoring (PRM). Additionally, tissue samples were harvested from the brain, heart, lung, kidney, liver, and duodenum of rats in each group for subsequent pathological examination. Results: The 72-h survival rate in the NM group was markedly higher than that observed in the EHS group. Pathological assessments indicated a notable reduction in thrombus formation within the brain, lungs, and liver in the NM group when compared to the EHS group. Furthermore, the NM group exhibited an elevated platelet count and a significant reduction in prothrombin time (PT) and activated partial thromboplastin time (APTT) relative to the EHS group. Proteomic profiling identified a total of 1,971 differentially expressed proteins, with 160 proteins being downregulated and 52 upregulated in the NM group as compared to the EHS group. PRM validation confirmed that the NM group significantly dampened the expression levels of key differential proteins, including ribosomal protein P2 (rpLP2), Histone 4c16 (H4c16), neutrophilic granule protein (NGP), and inositol monophosphatase 1 (Impa1), which are implicated in anti-inflammatory responses, suppression of immune-mediated thrombosis, and enhancement of cellular metabolism. Conclusion: NM mitigates coagulopathy, alleviates thrombus burden, and improves the 72-h survival rate in EHS rats through the modulation of differentially expressed proteins, specifically rpLP2, H4c16, NGP, and Impa1.
